README revision 318:b87875789600
1README: 2 This file should be located at the top of the OpenJDK Mercurial root 3 repository. This root repository will include a "make" directory, 4 and a Makefile for building the entire OpenJDK. 5 A full OpenJDK repository set (forest) should also include the following 6 6 nested repositories: 7 "jdk", "hotspot", "langtools", "corba", "jaxws" and "jaxp". 8 There are also several source downloads for the jax* repositories that 9 will be needed. 10 11 This one root repository can be obtained with something like: 12 hg clone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7 13 To make sure you have all the nested repositories, you can run: 14 cd openjdk7 && sh ./get_source.sh 15 (This is identical to using the Mercurial Forest Extension command 16 'hg fclone http://hg.openjdk.java.net/jdk7/jdk7 openjdk7'). 17 People unfamiliar with Mercurial should read the first few chapters of 18 the Mercurial book: http://hgbook.red-bean.com/read/ 19 20 See http://openjdk.java.net/ for more information about the OpenJDK. 21 22Simple Build Instructions: 23 24 0. Get the necessary system software/packages installed on your system, see 25 http://hg.openjdk.java.net/jdk7/build/raw-file/tip/README-builds.html 26 27 1. If you don't have a jdk6 installed, download and install a JDK 6 from 28 http://java.sun.com/javase/downloads/index.jsp 29 Set the environment variable ALT_BOOTDIR to the location of JDK 6. 30 31 2. Check the sanity of doing a build with your current system: 32 make sanity 33 See README-builds.html if you run into problems. 34 35 3. Do a complete build of the OpenJDK: 36 make all 37 The resulting JDK image should be found in build/*/j2sdk-image 38 39where make is GNU make 3.81 or newer, /usr/bin/make on Linux usually 40is 3.81 or newer. 41 42Complete details are available in README-builds.html. 43
